CLIFFORD ROBERT STEPHEN JOHN HALL, OF LONDON, ENGLAND.

PIANOFORTE.

SPECFICATION forming part of Letters Patent No. 666,138, dated. January15, 1901.

Application filed August 14, 1900. Serial No. 26,892. (No model.)

To @ZZ whom, t may concern.-

Be it known that I, CLIFFORD RQBERT STE- PHEN JOHN HALLE, a subject ofthe Queen of Great Britain, residing at 50 Lincolns Inn Fields, London,England, have invented certain new and useful Improvements in orConnected with Pianofortes, of which the following is a specification.

The object of my invention is to provide a means by which grand orhorizontal pianofortes may be provided with down-striking actions andthe arrangements for tuning may be of the simplest kind, while the barsof resistance shall be underneath the sound-board instead of over,thereby insuring a better and more even tone and a larger amount ofsoundboard under the treble part of the bridge.

The accompanying drawing will readily eX` plain my invention.

The wrest-plank 7c is at right angles to the sound-board j.

b is the end ofl one of the iron resistancebars of the frame.

m is one of the bolts by which the wrestplank is fixed to the bar Z. A

n is a strong plate of iron or plank of Wood upon which the bridge p isfixed. This plate or plank is supported on bearing-blocks fastenedbetween the same and the bar Z onto the back of the Wrest-plank, andthese blocks also offer support to the sound-board The tuning-pins t tpass out between the prolongwires d, which connect the end of the key awith the lever e, which has the hopper f centered onto it.

The hammer g is pivoted at a to a piece o, projecting from a bar w, towhich the spring s is fixed for supporting the hammer at the stock Thelever e is also in connection with the horizon tal dam per-lever h, thisbeing pivoted to an extension t' of the bar e', a pivoted bar y beingpivoted to the bar ,e for operation on the damper-lever h to lift thedamper q from the string r for the loud-pedal.

o represents the usual checks arranged upon Wires.

Other actions may be employed, those shown serving only as an elevationfor oonnecting same with my invention.

What I olaim, and desire to secure by Letters Patent, is-

1. In a piano, a wrest-plank at right angles to the sound-board of thepiano, a down-striking action, wires connecting the action to the keys,and tu ning-pins extending between the said wires and parallel with thesaid keys.

2. In a piano, a sound-board above the resistance-bars thereof, awrest-plank mounted at right angles to said board, a down-strikingaction, wires' connecting the action to the keys, and tuning-pinsextending between the said wires and parallel with the said keys.

3. In a piano, a downstriking action connected by prolong-wires to thekeys thereof, and a wrest-plank mounted at right angles to thesound-board of the piano and provided with tuning-pins extending betweenthe said wires to permit of tuning the piano from the front thereof.

4. In a piano, a down-striking action connected by prolong-wires to thekeys thereof, a sound-board mounted above the resistancebars, and awrest-plank at right angles to the said board and provided withtuning-pins eX- tending between the said wires and parallel with saidkeys.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
